What is the difference between alogia and aphasia

Apraxia of speech verbal apraxia is difficulty initiating and executing voluntary movement patterns necessary to produce speech when there is no paralysis or weakness of speech muscles. This involves difficulty voluntarily moving the muscles of the lips, throat, soft palate and tongue for purposes other than speech, such as smiling or whistling.

From a Research Domain Criteria RDoC perspective, it would be critical to determine whether these symptoms manifest similarly across diagnostic groups--as they may share common pathophysiological underpinnings.

The present study employed computerized acoustic analysis of speech produced in reaction to a range of visual stimuli in 48 stable outpatients with schizophrenia and mood disorders to offer preliminary understanding of this issue. Speaking assessments were administered 1 week-apart to examine how temporal stability might vary as a function of clinical diagnosis and symptom severity.

More specifically, it involves using fewer words, answering only what is directly asked, and speaking in a way that may be vague, repetitive, or overly concrete.

Alogia can be a symptom of various conditions, but it is most commonly associated with schizophrenia and is considered a "negative symptom," meaning that it takes away the ability to do something. If you are living with alogia, or know somebody who is, you will know that it can impair your ability to hold conversations and may lead to social isolation.

For this reason, it is an important symptom to understand, in terms of how to manage and cope as best you can. While most symptoms related to alogia are considered "negative" symptoms of schizophrenia that appear early in the course of the illness before a psychotic break, such as up to 1 to 3 years prior , alogia actually involves both positive and negative symptoms.

The positive symptoms emerge when there is poverty in the content of speech meaning that it becomes disorganized or incoherent. The negative symptoms relate to things like thought blocking, response latency, and poverty of speech. About 15 to 30 percent of those with schizophrenia have negative symptoms.

These are described in more detail below. To summarize, alogia is one of five types of negative symptoms that are present in schizophrenia blunted affect, anhedonia, asociality, and avolition are the other four. Alogia can be caused by schizophrenia or by other illnesses such as severe depression, bipolar disorder , traumatic brain injury, dementia , Alzheimer's, or schizotypal disorder. Alogia can also be a secondary effect, resulting from primary symptoms such as psychosis or anxiety. For example, you might choose not to speak, because there are voices in your head threatening you if you do.

In order to determine that alogia is caused by schizophrenia, it is necessary to first rule out other organic mental disorders. In the case of schizophrenia, it is considered a negative symptom related to the illness.

In contrast, in the case of illnesses involving dysfunction of the central nervous system, such as what is found with dementia or other illnesses that involve mental deficiency, alogia has a different cause. Alogia may even appear in those without a mental illness, as a result of a disruption in thought processes due to extreme stress or fatigue.

In this sense, alogia may appear on a continuum from mild to severe depending on the source of the symptoms. In the case of schizophrenia, alogia involves a disruption in the thought process that leads to a lack of speech and issues with verbal fluency.

For this reason, it is thought that alogia that appears as part of schizophrenia may result from disorganized semantic memory.

What's more, it's believed that this may be caused by brain dysfunction which causes the semantic store to degrade, which is the part of the brain that helps you to process language and the meaning of words. This explains why those with alogia produce fewer words overall and have trouble with finding the words to say what they want to say. This suggests once again that alogia related to schizophrenia is due to semantic memory disorganization.

In summary, alogia seems to be related to how your brain obtains words and meanings from your long-term memory stores. When different parts of the brain have difficulty communicating with each other, this can create the symptoms that manifest as alogia.

Clearly more research is needed to fully understand the cause and effect; however, if you live with alogia, know that this is most likely a primary symptom of schizophrenia and not simply an after-effect.

In other words, it's not that you just need to "try harder" or that a friend or relative needs to try harder, if you know someone with this illness. Below is an example of a conversation with someone with alogia. Following that is an example of a conversation with someone without alogia. Notice that there are differences in how much information is spontaneously offered when asked questions.

Alogia Example 2 incoherent speech, vague, little information actually provided. Q: Why do you work as a janitor? A: To explain that Non-Alogia Example. Q: It's good money and I like working nights. Not too many people around and it's quiet.

Treatment for alogia follows along with treatment for the underlying condition.
